题目链接:uva 616 - Coconuts, Revisited
题目大意:题目背景和uva 10726是一样的,只是这道题目是给出n,表示椰子的个数,并且猴子的个数为1,问说是否能找到满足的人数,并且要求人数尽量大。
解题思路:枚举人数,然后根据uva 10726推出的公式去求出最后剩下的椰子是否满足平分等判断。
#include <cstdio> #include <cstring> #include <cmath> #include <iostream> #include <algorithm> using namespace std; typedef long long ll; ll s; bool judge () { for (ll i = 12; i > 1; i--) { ll b = i - 1; ll t = (ll)pow(i, i); if ((s + b) % t) continue; ll k = (s + b) / t; ll p = (ll)pow(b, i); ll q = k * p - b; if (q % i) continue; printf("%lld people and 1 monkey\n", i); return false; } return true; } int main () { while (scanf("%lld", &s) == 1 && s != -1) { printf("%lld coconuts, ", s); if (judge ()) printf("no solution\n"); } return 0; }
